Let's assume there's a inode (ie ino 261) with i_count 1 is called by iput(), and there's a concurrent thread calling generic_shutdown_super(). cpu0: cpu1: iput() // i_count is 1 ->spin_lock(inode) ->dec i_count to 0 ->iput_final() generic_shutdown_super() ->__inode_add_lru() ->evict_inodes() // cause some reason[2] ->if (atomic_read(inode->i_count)) continue; // return before // inode 261 passed the above check // list_lru_add_obj() // and then schedule out ->spin_unlock() // note here: the inode 261 // was still at sb list and hash list, // and I_FREEING|I_WILL_FREE was not been set btrfs_iget() // after some function calls ->find_inode() // found the above inode 261 ->spin_lock(inode) // check I_FREEING|I_WILL_FREE // and passed ->__iget() ->spin_unlock(inode) // schedule back ->spin_lock(inode) // check (I_NEW|I_FREEING|I_WILL_FREE) flags, // passed and set I_FREEING iput() ->spin_unlock(inode) ->spin_lock(inode) ->evict() // dec i_count to 0 ->iput_final() ->spin_unlock() ->evict() Now, we have two threads simultaneously evicting the same inode, which may trigger the BUG(inode->i_state & I_CLEAR) statement both within clear_inode() and iput(). To fix the bug, recheck the inode->i_count after holding i_lock. Because in the most scenarios, the first check is valid, and the overhead of spin_lock() can be reduced. If there is any misunderstanding, please let me know, thanks. [1]: https://lore.kernel.org/linux-btrfs/000000000000eabe1d0619c48986@google.com/ [2]: The reason might be 1. SB_ACTIVE was removed or 2. mapping_shrinkable() return false when I reproduced the bug.

[PATCH OLK-5.10] nilfs2: fix potential deadlock with newly created symlinks
by Xiang Yang 25 Nov '24

25 Nov '24

From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> stable inclusion from stable-v5.10.229 commit c72e0df0b56c1166736dc8eb62070ebb12591447 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB379T CVE: CVE-2024-50229 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit b3a033e3ecd3471248d474ef263aadc0059e516a upstream. Syzbot reported that page_symlink(), called by nilfs_symlink(), triggers memory reclamation involving the filesystem layer, which can result in circular lock dependencies among the reader/writer semaphore nilfs->ns_segctor_sem, s_writers percpu_rwsem (intwrite) and the fs_reclaim pseudo lock. This is because after commit 21fc61c73c39 ("don't put symlink bodies in pagecache into highmem"), the gfp flags of the page cache for symbolic links are overwritten to GFP_KERNEL via inode_nohighmem(). This is not a problem for symlinks read from the backing device, because the __GFP_FS flag is dropped after inode_nohighmem() is called. However, when a new symlink is created with nilfs_symlink(), the gfp flags remain overwritten to GFP_KERNEL. Then, memory allocation called from page_symlink() etc. triggers memory reclamation including the FS layer, which may call nilfs_evict_inode() or nilfs_dirty_inode(). And these can cause a deadlock if they are called while nilfs->ns_segctor_sem is held: Fix this issue by dropping the __GFP_FS flag from the page cache GFP flags of newly created symlinks in the same way that nilfs_new_inode() and __nilfs_read_inode() do, as a workaround until we adopt nofs allocation scope consistently or improve the locking constraints.

[PATCH openEuler-1.0-LTS] io_uring/rw: fix missing NOWAIT check for O_DIRECT start write
by Baokun Li 23 Nov '24

23 Nov '24

From: Jens Axboe <axboe(a)kernel.dk> stable inclusion from stable-v5.10.230 commit 485d9232112b17f389b29497ff41b97b3189546b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB5KQC CVE: CVE-2024-53052 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- Commit 1d60d74e852647255bd8e76f5a22dc42531e4389 upstream. When io_uring starts a write, it'll call kiocb_start_write() to bump the super block rwsem, preventing any freezes from happening while that write is in-flight. The freeze side will grab that rwsem for writing, excluding any new writers from happening and waiting for existing writes to finish. But io_uring unconditionally uses kiocb_start_write(), which will block if someone is currently attempting to freeze the mount point. This causes a deadlock where freeze is waiting for previous writes to complete, but the previous writes cannot complete, as the task that is supposed to complete them is blocked waiting on starting a new write. This results in the following stuck trace showing that dependency with the write blocked starting a new write: task:fio state:D stack:0 pid:886 tgid:886 ppid:876 Call trace: __switch_to+0x1d8/0x348 __schedule+0x8e8/0x2248 schedule+0x110/0x3f0 percpu_rwsem_wait+0x1e8/0x3f8 __percpu_down_read+0xe8/0x500 io_write+0xbb8/0xff8 io_issue_sqe+0x10c/0x1020 io_submit_sqes+0x614/0x2110 __arm64_sys_io_uring_enter+0x524/0x1038 invoke_syscall+0x74/0x268 el0_svc_common.constprop.0+0x160/0x238 do_el0_svc+0x44/0x60 el0_svc+0x44/0xb0 el0t_64_sync_handler+0x118/0x128 el0t_64_sync+0x168/0x170 INFO: task fsfreeze:7364 blocked for more than 15 seconds.

For normal issue where IOCB_NOWAIT would always be set, this returns -EAGAIN which will have io_uring core issue a blocking attempt of the write. That will in turn also get completions run, ensuring forward progress. Since freezing requires CAP_SYS_ADMIN in the first place, this isn't something that can be triggered by a regular user.

[PATCH OLK-6.6] RDMA/hns: Fix bonding failure due to wrong reset_state
by Chengchang Tang 22 Nov '24

22 Nov '24

From: Junxian Huang <huangjunxian6(a)hisilicon.com> driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IB3K00 ---------------------------------------------------------------------- When roce driver is removed during reset, the reset flow of roce may not be fully completed. This may lead to the reset_state of roce handler stored in nic driver remaining in a middle state, such as HNS_ROCE_STATE_RST_DOWN or HNS_ROCE_STATE_RST_UNINIT. The reset_state won't be cleared even if roce driver is re-inited. This cause that roce bonding which currently relies on reset_state fails in this case. Replace the reset detection for bonding with nic APIs (.ae_dev_resetting() and .get_hw_reset_stat()), just like the reset detection elsewhere in roce driver. Fixes: 26d71e7c13cf ("RDMA/hns: Fix the concurrency error between bond and reset.")

[PATCH OLK-6.6] rxrpc: Fix a race between socket set up and I/O thread creation
by Dong Chenchen 22 Nov '24

22 Nov '24

From: David Howells <dhowells(a)redhat.com> stable inclusion from stable-v6.6.55 commit cdf4bbbdb956d7426f687f38757ebca2a2759a0f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYR8U CVE: CVE-2024-49864 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit bc212465326e8587325f520a052346f0b57360e6 upstream. In rxrpc_open_socket(), it sets up the socket and then sets up the I/O thread that will handle it. This is a problem, however, as there's a gap between the two phases in which a packet may come into rxrpc_encap_rcv() from the UDP packet but we oops when trying to wake the not-yet created I/O thread. As a quick fix, just make rxrpc_encap_rcv() discard the packet if there's no I/O thread yet. A better, but more intrusive fix would perhaps be to rearrange things such that the socket creation is done by the I/O thread.

[PATCH OLK-6.6] net/mlx5e: Fix crash caused by calling __xfrm_state_delete() twice
by Dong Chenchen 22 Nov '24

From: Jianbo Liu <jianbol(a)nvidia.com> stable inclusion from stable-v6.6.55 commit fab615ac9fcb8589222303099975d464d8857527 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYR9F CVE: CVE-2024-49953 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 7b124695db40d5c9c5295a94ae928a8d67a01c3d ] The km.state is not checked in driver's delayed work. When xfrm_state_check_expire() is called, the state can be reset to XFRM_STATE_EXPIRED, even if it is XFRM_STATE_DEAD already. This happens when xfrm state is deleted, but not freed yet. As __xfrm_state_delete() is called again in xfrm timer, the following crash occurs. To fix this issue, skip xfrm_state_check_expire() if km.state is not XFRM_STATE_VALID.

However, due to rtw89_wow_resume() return failure, it will cause the add interface flow to be executed again, resulting in a double add list and causing a kernel panic. Therefore, we have added a check to prevent double adding of the list. list_add double add: new=ffff99d6992e2010, prev=ffff99d6992e2010, next=ffff99d695302628. ------------[ cut here ]------------ kernel BUG at lib/list_debug.c:37! invalid opcode: 0000 [#1] PREEMPT SMP NOPTI CPU: 0 PID: 9 Comm: kworker/0:1 Tainted: G W O 6.6.30-02659-gc18865c4dfbd #1 770df2933251a0e3c888ba69d1053a817a6376a7 Hardware name: HP Grunt/Grunt, BIOS Google_Grunt.11031.169.0 06/24/2021 Workqueue: events_freezable ieee80211_restart_work [mac80211] RIP: 0010:__list_add_valid_or_report+0x5e/0xb0 Code: c7 74 18 48 39 ce 74 13 b0 01 59 5a 5e 5f 41 58 41 59 41 5a 5d e9 e2 d6 03 00 cc 48 c7 c7 8d 4f 17 83 48 89 c2 e8 02 c0 00 00 <0f> 0b 48 c7 c7 aa 8c 1c 83 e8 f4 bf 00 00 0f 0b 48 c7 c7 c8 bc 12 RSP: 0018:ffffa91b8007bc50 EFLAGS: 00010246 RAX: 0000000000000058 RBX: ffff99d6992e0900 RCX: a014d76c70ef3900 RDX: ffffa91b8007bae8 RSI: 00000000ffffdfff RDI: 0000000000000001 RBP: ffffa91b8007bc88 R08: 0000000000000000 R09: ffffa91b8007bae0 R10: 00000000ffffdfff R11: ffffffff83a79800 R12: ffff99d695302060 R13: ffff99d695300900 R14: ffff99d6992e1be0 R15: ffff99d6992e2010 FS: 0000000000000000(0000) GS:ffff99d6aac00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 000078fbdba43480 CR3: 000000010e464000 CR4: 00000000001506f0 Call Trace: <TASK> ?

After establishing all its connections, the information is exchanged between the client and server through the info_req message. During this exchange, it is essential that all connections have been established, and the state of the RTRS srv path is CONNECTED. So add these sanity checks, to make sure we detect and abort process in error scenarios to avoid null pointer deref.

Once the timer is started, there is a risk of a race condition if the module or device is removed, triggering the ether3_remove function to perform cleanup. The sequence of operations that may lead to a UAF bug is as follows: CPU0 CPU1 | ether3_ledoff ether3_remove | free_netdev(dev); | put_devic | kfree(dev); | | ether3_outw(priv(dev)->regs.config2 |= CFG2_CTRLO, REG_CONFIG2); | // use dev Fix it by ensuring that the timer is canceled before proceeding with the cleanup in ether3_remove.

[PATCH OLK-6.6] netfilter: br_netfilter: fix panic with metadata_dst skb
by Dong Chenchen 22 Nov '24

22 Nov '24

From: Andy Roulin <aroulin(a)nvidia.com> stable inclusion from stable-v6.6.57 commit 3453f5839420bfbb85c86c61e49f49ffd0f041c4 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYREA CVE: CVE-2024-50045 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit f9ff7665cd128012868098bbd07e28993e314fdb ] Fix a kernel panic in the br_netfilter module when sending untagged traffic via a VxLAN device. This happens during the check for fragmentation in br_nf_dev_queue_xmit. It is dependent on: 1) the br_netfilter module being loaded; 2) net.bridge.bridge-nf-call-iptables set to 1; 3) a bridge with a VxLAN (single-vxlan-device) netdevice as a bridge port; 4) untagged frames with size higher than the VxLAN MTU forwarded/flooded When forwarding the untagged packet to the VxLAN bridge port, before the netfilter hooks are called, br_handle_egress_vlan_tunnel is called and changes the skb_dst to the tunnel dst. The tunnel_dst is a metadata type of dst, i.e., skb_valid_dst(skb) is false, and metadata->dst.dev is NULL. Then in the br_netfilter hooks, in br_nf_dev_queue_xmit, there's a check for frames that needs to be fragmented: frames with higher MTU than the VxLAN device end up calling br_nf_ip_fragment, which in turns call ip_skb_dst_mtu. The ip_dst_mtu tries to use the skb_dst(skb) as if it was a valid dst with valid dst->dev, thus the crash. This case was never supported in the first place, so drop the packet instead.

[PATCH openEuler-22.03-LTS-SP1] llc: verify mac len before reading mac header
by Dong Chenchen 22 Nov '24

22 Nov '24

From: Willem de Bruijn <willemb(a)google.com> stable inclusion from stable-v5.10.201 commit 3a2653828ffc6101aef80bf58d5b77484239f779 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9RG0B CVE: CVE-2023-52843 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 7b3ba18703a63f6fd487183b9262b08e5632da1b ] LLC reads the mac header with eth_hdr without verifying that the skb has an Ethernet header. Syzbot was able to enter llc_rcv on a tun device. Tun can insert packets without mac len and with user configurable skb->protocol (passing a tun_pi header when not configuring IFF_NO_PI). BUG: KMSAN: uninit-value in llc_station_ac_send_test_r net/llc/llc_station.c:81 [inline] BUG: KMSAN: uninit-value in llc_station_rcv+0x6fb/0x1290 net/llc/llc_station.c:111 llc_station_ac_send_test_r net/llc/llc_station.c:81 [inline] llc_station_rcv+0x6fb/0x1290 net/llc/llc_station.c:111 llc_rcv+0xc5d/0x14a0 net/llc/llc_input.c:218 __netif_receive_skb_one_core net/core/dev.c:5523 [inline] __netif_receive_skb+0x1a6/0x5a0 net/core/dev.c:5637 netif_receive_skb_internal net/core/dev.c:5723 [inline] netif_receive_skb+0x58/0x660 net/core/dev.c:5782 tun_rx_batched+0x3ee/0x980 drivers/net/tun.c:1555 tun_get_user+0x54c5/0x69c0 drivers/net/tun.c:2002 Add a mac_len test before all three eth_hdr(skb) calls under net/llc. There are further uses in include/net/llc_pdu.h. All these are protected by a test skb->protocol == ETH_P_802_2. Which does not protect against this tun scenario. But the mac_len test added in this patch in llc_fixup_skb will indirectly protect those too. That is called from llc_rcv before any other LLC code. It is tempting to just add a blanket mac_len check in llc_rcv, but not sure whether that could break valid LLC paths that do not assume an Ethernet header. 802.2 LLC may be used on top of non-802.3 protocols in principle. The below referenced commit shows that used to, on top of Token Ring. At least one of the three eth_hdr uses goes back to before the start of git history. But the one that syzbot exercises is introduced in this commit. That commit is old enough (2008), that effectively all stable kernels should receive this.

At insert_delayed_ref() if we need to update the action of an existing ref to BTRFS_DROP_DELAYED_REF, we delete the ref from its ref head's ref_add_list using list_del(), which leaves the ref's add_list member not reinitialized, as list_del() sets the next and prev members of the list to LIST_POISON1 and LIST_POISON2, respectively. If later we end up calling drop_delayed_ref() against the ref, which can happen during merging or when destroying delayed refs due to a transaction abort, we can trigger a crash since at drop_delayed_ref() we call list_empty() against the ref's add_list, which returns false since the list was not reinitialized after the list_del() and as a consequence we call list_del() again at drop_delayed_ref(). This results in an invalid list access since the next and prev members are set to poison pointers, resulting in a splat if CONFIG_LIST_HARDENED and CONFIG_DEBUG_LIST are set or invalid poison pointer dereferences otherwise. So fix this by deleting from the list with list_del_init() instead.

[PATCH OLK-6.6] tpm: Lock TPM chip in tpm_pm_suspend() first

22 Nov '24

From: Jarkko Sakkinen <jarkko(a)kernel.org> mainline inclusion from mainline-v6.12-rc1 commit 9265fed6db601ee2ec47577815387458ef4f047a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB5KRG CVE: CVE-2024-53085 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Setting TPM_CHIP_FLAG_SUSPENDED in the end of tpm_pm_suspend() can be racy according, as this leaves window for tpm_hwrng_read() to be called while the operation is in progress. The recent bug report gives also evidence of this behaviour. Aadress this by locking the TPM chip before checking any chip->flags both in tpm_pm_suspend() and tpm_hwrng_read(). Move TPM_CHIP_FLAG_SUSPENDED check inside tpm_get_random() so that it will be always checked only when the lock is reserved.

[PATCH OLK-5.10 V1] sched/topology: Prevent race condition in sched_domain topology
by Zicheng Qu 22 Nov '24

22 Nov '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB485D -------------------------------- A race condition in `build_sched_domains() -> build_sched_domain() -> sd_init()` can lead to a null pointer dereference when `tl->data` is accessed. This occurs because `build_sched_domains() -> alloc_state()` may skip memory allocation for `tl->data` based on `tl->flags` and `SDTL_SKIP`, which can be influenced by concurrent modifications through `sched_cluster_handler()`, supported by the feature named "scheduler: Add runtime knob sysctl_sched_cluster". The issue arises when `sysctl_sched_cluster()` is modified via `/proc/sys/kernel/sched_cluster`, affecting `tl->flags` through `sched_cluster_handler() -> set_sched_cluster()`. This can lead to an inconsistent state where `tl->data` is expected to be non-null in `sd_init()`, but was not allocated in `alloc_state()` before `sd_init()`. To resolve this, lock `sched_domains_mutex` before calling `set_sched_cluster()`. This ensures that changes to `tl->flags` do not interfere with the memory allocation process in `build_sched_domains()`.

[PATCH OLK-5.10 00/19] blk-mq/scsi: tracking device queue depth via sbitmap
by Zheng Qixing 22 Nov '24

22 Nov '24

Linux mainline-5.13 uses sbitmap to track the queue depth of SCSI devices. This patch set backports the mainline patches to OLK-5.10 and fixes some KABI issues. Tests on scsi_debug show that this method can improve IO performance by more than 30%.

[PATCH OLK-6.6] bpftool: Fix undefined behavior in qsort(NULL, 0, ...)

From: Kuan-Wei Chiu <visitorckw(a)gmail.com> stable inclusion from stable-v6.6.55 commit c2d9f9a7837ab29ccae0c42252f17d436bf0a501 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB0MX4 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit f04e2ad394e2755d0bb2d858ecb5598718bf00d5 ] When netfilter has no entry to display, qsort is called with qsort(NULL, 0, ...). This results in undefined behavior, as UBSan reports: net.c:827:2: runtime error: null pointer passed as argument 1, which is declared to never be null Although the C standard does not explicitly state whether calling qsort with a NULL pointer when the size is 0 constitutes undefined behavior, Section 7.1.4 of the C standard (Use of library functions) mentions: "Each of the following statements applies unless explicitly stated otherwise in the detailed descriptions that follow: If an argument to a function has an invalid value (such as a value outside the domain of the function, or a pointer outside the address space of the program, or a null pointer, or a pointer to non-modifiable storage when the corresponding parameter is not const-qualified) or a type (after promotion) not expected by a function with variable number of arguments, the behavior is undefined." To avoid this, add an early return when nf_link_info is NULL to prevent calling qsort with a NULL pointer.

[PATCH OLK-6.6] tpm: Lock TPM chip in tpm_pm_suspend() first
by Chen Zhongjin 21 Nov '24

21 Nov '24

From: Jarkko Sakkinen <jarkko(a)kernel.org> mainline inclusion from mainline-v6.12-rc1 commit 9265fed6db601ee2ec47577815387458ef4f047a category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB5KRG CVE: CVE-2024-53085 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- Setting TPM_CHIP_FLAG_SUSPENDED in the end of tpm_pm_suspend() can be racy according, as this leaves window for tpm_hwrng_read() to be called while the operation is in progress. The recent bug report gives also evidence of this behaviour. Aadress this by locking the TPM chip before checking any chip->flags both in tpm_pm_suspend() and tpm_hwrng_read(). Move TPM_CHIP_FLAG_SUSPENDED check inside tpm_get_random() so that it will be always checked only when the lock is reserved.

[PATCH OLK-6.6] bpftool: Fix undefined behavior in qsort(NULL, 0, ...)

This results in undefined behavior, as UBSan reports: net.c:827:2: runtime error: null pointer passed as argument 1, which is declared to never be null Although the C standard does not explicitly state whether calling qsort with a NULL pointer when the size is 0 constitutes undefined behavior, Section 7.1.4 of the C standard (Use of library functions) mentions: "Each of the following statements applies unless explicitly stated otherwise in the detailed descriptions that follow: If an argument to a function has an invalid value (such as a value outside the domain of the function, or a pointer outside the address space of the program, or a null pointer, or a pointer to non-modifiable storage when the corresponding parameter is not const-qualified) or a type (after promotion) not expected by a function with variable number of arguments, the behavior is undefined." To avoid this, add an early return when nf_link_info is NULL to prevent calling qsort with a NULL pointer.

For example, consider a trie with max_prefixlen is 8, and the nodes with key 0x00/0, 0x00/1, 0x00/2, ... 0x00/8 inserted. Subsequent calls to trie_get_next_key with _key with .prefixlen = 8 make 9 nodes be written on the node stack with size 8.

This attribute is used in bounds checking, and if it is not set before the array is filled, then the bounds sanitizer will issue a warning or a kernel panic if CONFIG_UBSAN_TRAP is set. This patch sets the size of the widgets list calculated with list_for_each as the initial value for num_widgets as it is used for allocating memory for the array.
